[0031] The indicator 2 is disposed in the middle of the main scale 1 and extends in a direction perpendicular to the length of the main scale 1 , dividing the main scale 1 into a first portion 11 and a second portion 12 .

[0032] The first movable caliper 3 is movably disposed on the first portion 11 of the main scale 1 , and an edge of the first movable caliper 3 is provided with a first limiter that cooperates with the main scale 1 .

[0033] The second movable caliper 4 is movably arranged on the second portion 12 of the main scale 1 , and the edge of the second movable caliper 4 is provided with a second limiting member matched with the main scale 1 .

[0034] The first movable caliper 3 and the second movable caliper 4 can move toward or away from each other so as to be aligned with the upper and lower ends of the patient's patella.

[0035] One end of the first elastic cord 51 is fixed on the surface of the first movable caliper 3 close to the main scale 1, and the other end is fixed on the surface of the second movable caliper 4 away from the main scale 1. One end of the second elastic cord 52 is fixed on the surface of the first movable caliper 3 away from the main scale 1, and the other end is fixed on the surface of the second movable caliper 4 close to the main scale 1. The intersection of the first elastic cord 51 and the second elastic cord 52 forms an indication node. Although the first elastic cord 51 and the second elastic cord 52 will stretch or shrink in the process of the first movable caliper 3 and the second movable caliper 4 approaching or moving away from each other, the indication node formed by the intersection of the two is always located at the midpoint between the opposite edges of the first movable caliper 3 and the second movable caliper 4.

[0036] The first soft tape measure 61 is arranged at the edge of the first part 11 and is used for measuring the leg circumference of the thigh.

[0037] The second soft tape measure 62 is disposed at the edge of the second portion 12 and is used to measure the circumference of the calf.

[0038] When in use, the main ruler 1 can be adjusted to be parallel to the patient's leg, and then the first movable caliper 3 and the second movable caliper 4 can be adjusted to be aligned with the upper and lower ends of the patient's patella, respectively. In this state, the indicating node at the intersection of the first elastic rope 51 and the second elastic rope 52 is just aligned with the midpoint of the patient's patella, and then the main ruler 1 is moved relative to the first movable caliper 3 and the second movable caliper 4 until the indicating member 2 points to the indicating node, and the first movable caliper 3 and the second movable caliper 4 are fixed by the first limiter and the second limiter, respectively. In this state, the first soft ruler 61 is aligned with the thigh circumference measurement position, and the second soft ruler 62 is aligned with the calf circumference measurement position, and the patient's thigh circumference and calf circumference can be measured by the first soft ruler 61 and the second soft ruler 62, respectively. Such a setting can realize the rapid positioning of the measurement positions of the first soft ruler 61 and the second soft ruler 62 according to the leg circumference measurement standard, and the operation is simple, which improves the measurement accuracy and measurement efficiency.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the indicator 2 is aligned with the zero mark 10 of the main ruler 1, the length of the first part 11 is 15 cm, and the length of the second part 12 is 10 cm. The indicator 2 can be a pointer or an indicator rod, which is used to indicate the alignment with the indicator node. The length of the first part 11 is 15 cm, and the length of the second part 12 is 10 cm, which can meet the leg circumference measurement standard, so that the first soft ruler 61 located at the edge of the first part 11 and the second soft ruler 62 located at the edge of the second part 12 can be aligned with the thigh circumference measurement position and the calf measurement position respectively.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the first part 11 is marked with scale lines and scale indications that gradually increase from the zero scale line 10 to the edge. The second part 12 is marked with scale lines and scale indications that gradually increase from the zero scale line 10 to the edge. Such a setting is conducive to the operator observing the distance between the first movable caliper 3 and the second movable caliper 4 and the zero scale line, so as to adjust the distance between the first movable caliper 3 and the second movable caliper 4 and the zero scale line to be the same, so as to ensure that the indicating node where the first elastic rope 51 and the second elastic rope 52 located between the first movable caliper 3 and the second movable caliper 4 intersect is located at the center point between the first movable caliper 3 and the second movable caliper 4.

[0041] The first elastic rope 51 and the second elastic rope 52 have the same length in a natural state and can be completely the same rubber band.

The first movable caliper 3 and the second movable caliper 4 are arranged opposite to each other, one right-angled side of the first movable caliper 3 is arranged parallel to the main scale 1, and the other right-angled side faces the second movable caliper 4, and one right-angled side of the second movable caliper is arranged parallel to the main scale 1, and the other right-angled side faces the first movable caliper 3. The two parallel right-angled sides make it easier to align with the upper and lower ends of the patella, and at the same time, it is more conducive to ensuring that the intersection of the first elastic rope 51 and the second elastic rope 52 is located at the midpoint between the first movable caliper 3 and the second movable caliper 4.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the first movable caliper 3 is arranged on the main scale 1 through the first sleeve 31, and the first position-limiting member includes a first base 32 and a first screwing member 33. The first base 32 is fixedly arranged on the first sleeve 31, and the first base 32 and the first sleeve 31 have a first through hole in communication, one end of the first through hole opens toward the main scale 1, and the first screwing member 33 extends from the other end of the first through hole. The first sleeve 31 is slidably matched with the main scale 1 through the inner hole, and the inner walls of the first base 32 and the first sleeve 31 are provided with a through first through hole, and the first screwing member 33 can abut against the main scale after extending from the first through hole, thereby limiting the position of the first sleeve 31.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the second movable caliper 4 is arranged on the main scale 1 through the second sliding sleeve 41, and the second limiting member includes a second base 42 and a second screwing member 43. The second base 42 is fixedly arranged on the second sliding sleeve 41, and the second base 42 and the second sliding sleeve 41 have a second through hole in communication, one end of the second through hole opens toward the main scale 1, and the second screwing member 43 extends from the other end of the second through hole. For the same reason, the second sliding sleeve 41 is slidably matched with the main scale 1 through the inner hole, and the second base 42 and the inner wall of the second sliding sleeve 41 are provided with a through second through hole, and the second screwing member 44 can abut against the main scale after extending from the second through hole, thereby limiting the second sliding sleeve 41.

[0045] The first through hole and the second through hole may be threaded holes, and the first tightening member 33 and the second tightening member 43 may be tightening screws.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the measuring direction of the first soft tape 61 is perpendicular to the length direction of the main tape 1, and the center point of the first soft tape 61 in the width direction is aligned with the 15 cm scale indication of the first part 11, thereby improving the measurement accuracy of the first soft tape 61 for the thigh circumference.
